Control the voice your caller hears

Independent voice controls

Raise or lower your pitch and adjust vocal character separately. Combining both controls lets you tailor the result to your speaking voice.

Continuous adjustment

Fine-tune the settings as you speak, with a range of combinations rather than a fixed set of preset voices.

Keep using your handset

CVX-PLUS sits between the phone base and handset. You speak into the handset microphone and listen through its earpiece.

Full description

How CVX-PLUS changes your voice

CVX-PLUS processes audio from the handset microphone before it reaches the other caller. Pitch control makes your voice higher or lower, while formant control changes the resonances that shape its character.

Both controls are independent and continuously variable. You can combine their settings to create different vocal characteristics and fine-tune the result while you speak.

Connect between the phone and handset

Disconnect the handset from the phone base and connect CVX-PLUS between them. Once connected, use the phone as usual: speak into the handset microphone and listen through the earpiece.

Adjust your voice as you talk

The controls remain within reach throughout the call. Keep your chosen settings for the entire conversation or gradually change pitch, vocal character, or both.

The result depends on your natural voice and the settings you choose. Continuous adjustment lets you find the combination you want without switching between a fixed number of preset voices.

USB or battery power

Power CVX-PLUS through the USB-A port on the back or use four AA batteries. Battery operation lets you use the voice changer without a USB power connection during calls.
